OBJECTIVES The aim of this study was to characterize and evaluate the clinical impact of untreated atherosclerotic disease after percutaneous coronary intervention (PCI) in patients with acute coronary syndromes (ACS). BACKGROUND Residual atherosclerotic disease after successful PCI may predispose future major adverse cardiovascular events (MACE). Compared with intravascular ultrasound (IVUS)...
INTRODUCTION AND OBJECTIVES Patients with acute coronary syndromes may have significantly stenotic nonculprit lesions that do not show complex lesion morphology. We investigated whether these lesions were prone to become unstable since they exist within a prothrombotic and inflammatory systemic milieu. PATIENTS AND METHOD We evaluated the clinical course of 150 patients after successful angio...
chronic total occlusion (cto) intervention is still a challenging problem. the aim of this study is to determine factors that affect pci results.the study was conducted on 72 patients in two centers. cto angioplasty was done by the antegrade approach from the femoral and/or radial approach. the role of age, gender, anatomical variations such as calcification, length of the lesion, proximal bend...
An autoperfusion balloon catheter was developed to allow passive myocardial perfusion during inflation through a central lumen and multiple side holes in the shaft proximal and distal to the balloon. We report its safety and efficacy in 11 patients undergoing elective angioplasty to a single coronary lesion. Each lesion was dilated three times with the autoperfusion inflation bracketed between ...
Background and purpose: Âim of this research is to study the effect of bridging collateral vessels (BÇVS) on the success of coronary angioplasty in patients with chronic total occlusion (ÇTÔ). Ïn coronary angioplasty of ÇTÔ cases, categorizing of lessions characteristics can be helpful in evaluation of success in angioplasty. There are controversies about the role of BÇVS in the rate of angio...
To determine the effects of coronary angioplasty on coronary flow reserve (CFR), we studied 32 patients before and immediately after single-vessel coronary angioplasty and 31 patients evaluated late after angioplasty (7.5 + 1.2 months, mean + SEM). The geometry (percent area stenosis and minimal cross-sectional area) of each lesion was determined by quantitative coronary angiography (Brown/Dodg...
This article comprised the data related to the research article entitled "Feasibility and usefulness of three-dimensional optical coherence tomography guidance for optimal side branch treatment in coronary bifurcation stenting" (Nagoshi et al., In press) [1]. In this article we reports details about two patterns of guide wire (GW) recrossing position after crossover stenting in bifurcation lesi...
BACKGROUND AND OBJECTIVES Stented segment length is a predictive factor for restenosis and stent thrombosis still in the drug-eluting stent (DES) era, and the benefit of routine intravascular ultrasound (IVUS) is still unclear. The aim of the present study was to investigate whether IVUS-guided percutaneous coronary intervention (PCI) improved the vascular outcomes as compared with conventional...
